Chris Fallows famous breach photographer

Chris Fallows spent a lot of time trying to get photographs of great white sharks breaching in the South African waters. This is a little clip of him photographing a large white shark completely airborne while hunting a seal. I didn't know that great whites only jump completely out of the water when hunting, in the South African waters near Seal Island. According to some other shark fans on You Tube it is because it has to do with the isoclimes (sp?) around seal island. The top layer is completely clear for about 3-5 meters, which means that the seals can see the sharks coming from a long way off. The layer below that is very cloudy, so the sharks have learned that to get food they need to come up very quickly from below. to get the pics they are towing a seal carcass behind.
